Something I noticed today. I still have my satellite radio with the adaptor kit that works just fine with my original 2013 pioneer HU in my car. The updated touchscreen pioneer unit has the same 12 pin connector. So I plugged it in, and did the hold audio and turn parking lights on and off three times to get into the diagnostic mode. This is what I saw:
So, basically the HU knows that the satellite radio is there, they just aren't allowing us access to it, probably because Scion has an agreement with Aha radio. This annoys me.
